LG UA75006LA (IPS) vs Samsung QN90F / QN92F

It looks even more modest in the version with an IPS panel, where the peak brightness only reaches 250 nits. In practice, this means that a real sense of HDR effect is out of the question, and the materials being viewed resemble regular SDR. Similar to VA panels, the image behaves stably across most test patterns, but in demanding scenes with fine details, the television tends to slightly dim the picture. As a result, blacks appear a bit better, but at the cost of losing detail in bright elements. The absence of additional colour filters is also noticeable here. The UA7500 in the IPS version is neither a QLED nor a PFS LED panel, and the DCI-P3 colour gamut stops at 80%, which means that HDR films lack significant colour depth and appear quite flat.

Samsung QN90F can really shine with brightness. In our measurements, it reached even over 2200 nits, which directly translates to the viewing experience. In practice, this means that when a very bright scene appears in a film – for example, a sunrise in The Meg – the screen looks as if natural light is actually shining on us. This isn't just a number from a table, but a real sense of image intensity! However, the TV can't always deliver its full power. With smaller details, such as spotlights or lamps, brightness drops to 500–700 nits. This is a deliberate decision by the algorithms – by doing this, the contrast between large and small elements is better controlled, and the image doesn't lose balance. Importantly, this is still a huge improvement compared to last year's QN90D, where similar details were almost invisible, shining at just 200 nits. Here, the HDR effect is much more cohesive and credible. The only downside is the colours. The coverage of the DCI-P3 spectrum has plateaued at 91%, which can be considered a rather average result in this price range.

The Filmmaker mode on the LG UA7500 performs better than you might expect from such a budget television, but let’s not get carried away with admiration. The picture is put together quite sensibly and at first glance is not irritating; however, its weaknesses quickly become apparent. This is most noticeable in scenes with bright points – lamps in the background or reflections of light on skin are clearly oversaturated. The faces of characters often appear unnatural, as if they have been "blown out." Additionally, the default gamma setting brightens even the slightest details and causes the picture to lose subtlety in the darker areas. That said, for its price range, the UA7500 in factory mode provides a pretty decent starting point. However, it is clear that without additional adjustment, these issues won't be avoided, which is why – as with other televisions – we decided to see what could be achieved after calibration.

The colour reproduction in the QN90F was tested in Filmmaker mode and, as is usually the case with Samsung TVs, this mode proves to be the best starting point straight out of the box. However, this does not mean that we are dealing with an image free of flaws. The white balance in SDR and HDR content was surprisingly good – colours didn't drift in any direction and even in its factory settings it looked solid. However, a problem arose with the gamma and EOTF curves, which determine how the TV manages brightness. Here, the QN90F significantly brightened the entire image, causing the black levels and colours to lose their intensity, and the overall effect resembled that of an applied milky filter. Fortunately, Samsung, unlike many competitors in the miniLED world, provides users with plenty of tools to control settings that we won't find in other manufacturers, such as Chinese brands. Therefore, we decided to see if we could squeeze the full potential out of the QN90F because we know that such a high series is capable of much more.

The biggest improvement we noticed was when calibrating the mode intended for everyday SDR content. We managed to smoothly adjust the white balance in an acceptable manner and tame the issue of excessive brightening of small elements due to the gamma characteristics. As a result, the image gained consistency and a naturalness that was lacking in the factory settings. After such a correction, we can confidently say that for everyday television content, programmes, or materials from YouTube, the LG UA7500 performs really well – especially after professional calibration. The situation is somewhat different for HDR content. Here, calibration did manage to tame the white balance and slightly improve brightness management, however, the design limitations are immediately apparent. The lack of additional filters that expand the colour palette means that the most vibrant colours appear flat, and the image lacks the intensity one would expect from good HDR. In SDR, the UA7500 performs quite well, but in HDR – despite the corrections – it remains far behind, and this is a characteristic that one must accept when choosing this television.

After our adjustment of the settings, the QN90F showed what it’s really capable of – and we have to admit, it’s one of the best images we’ve seen on a miniLED screen this year. As we mentioned earlier, the white balance wasn’t a big issue even in the factory settings, but it was only after gamma calibration that we were able to get close to reference values. The same goes for HDR content, where the EOTF curve post-adjustment presents mature and consistent results. Indeed, in some films, you can notice that the smallest elements of the image are slightly brightened, and with a limited number of local dimming zones, there's still a risk of halo effect. However, it’s important to remember that such phenomena are characteristic of all miniLED TVs and it’s difficult to expect miracles even from the QN90F. The most important thing is that after calibration, the television displays an image that confidently competes with many OLED screens available on the market in terms of expressing the director's vision.

The version with the IPS panel performed noticeably worse here. Image scaling was uneven – this was especially evident in lower quality materials, where edges became jagged and the image looked less detailed. At times, there was also a sense of slight blurriness, which took away sharpness and made the overall picture seem less refined than in the VA version. The tonal smoothing function turned out to be a rescue. On medium settings, it worked quite well – it did not ruin the image with excessive softening, while also smoothing out colours in such a way that everyday content gained consistency. The difference was particularly noticeable with TV programs or streaming materials of poorer compression quality, where the television with the function enabled presented itself much better. This is one of those additions that are worth keeping active, as they significantly improve the reception of everyday materials.

QN90F handles upscaling very well. Materials in lower resolutions, even SD, are enhanced to a clear and sharp image, where a lot of background detail can be seen. This is a big advantage, as the TV makes older content or everyday television look significantly better than on most budget screens. However, the issue of overscan remains, which is the cropping of the screen edges that cannot be turned off on Samsungs. This can cause some subtitles on the screen to disappear or Auntie's face from the wedding on a VHS tape to be slightly cropped. 😉

The digital image processing also performs well. In the menu, we find a feature called "noise reduction," which can smooth tonal transitions and improve the viewing of lower quality materials, such as those from YouTube. In the medium setting, the effect is most beneficial – it doesn't heavily interfere with details while simultaneously eliminating the problem of "banding" in colours. However, it's worth noting that the feature can be quite aggressive and removes natural film grain in older movies, so it's best to use it sparingly.

LG UA7500 is a television with a 60 Hz panel, so it's hard to expect any excitement in this category. It's more of a screen intended for daily content or an evening movie session rather than for following fast-paced sports events or playing action games. It’s clear that the manufacturer designed this model specifically for that audience – and it performs well in that regard. We have the TruMotion function available, which is a motion smoother. It’s simple, has only one slider, but can make a noticeable difference. At the lower range, the image looks more raw and cinematic, while at higher values, the motion becomes smoother and more pleasurable to the eye.

QN90F has been equipped with a panel that has a maximum refresh rate of 165 Hz, and while this advantage will mainly be appreciated by PC gamers, it’s still worth highlighting. In movies or sports broadcasts, we are limited to the classic 120 Hz, but this is not a cause for concern. In practice, the additional motion smoother is more significant here. Thanks to the "Motion Clarity" setting, we can adjust the picture to our own preferences. The blur reduction option is responsible for fluidity and ghosting in sports. Meanwhile, the "judder reduction" function improves motion fluidity in productions recorded at 24 frames, namely films and series. If we set it high, the film looks smoother and more fluid than it was actually shot. Lower values, on the other hand, preserve its cinematic "rawness" with the visible film frame.

LG UA7500 is a TV that can be confidently recommended to "casual" gamers. While it doesn’t feature a 120 Hz panel or HDMI 2.1 ports, making full use of the potential of modern consoles isn’t something we can expect. However, the manufacturer has included several additions that can enhance the gaming experience. Notably, there's the Game Bar – a very nicely designed panel that allows quick access to and changes of the most important settings. From this panel, we have access to the ALLM mode (automatic switching to game mode), as well as frame synchronization, or VRR. The range of VRR is limited – it works from 48 to 60 Hz – but the mere presence of this feature in such an affordable TV leaves a positive impression.

Additionally, it also supports HGiG, which is a HDR calibration mode for games. It sounds good, but from our testing experience, we know that for the UA7500 this option doesn’t make much sense. The TV doesn't perform well with HDR, so paradoxically, we achieved better results with this mode turned off. This is another signal that the UA7500 is more of a screen for occasional gamers who value simplicity and convenience rather than for those looking for the full experience from the latest consoles.

QN90F has almost everything to become the perfect TV for gamers. Things like four HDMI ports, VRR, ALLM, and a refresh rate of up to 165 Hz need no reminder. It deserves high praise for the Game Motion Plus mode, Samsung's proprietary motion smoothing for games. Thanks to this, you can add a few "artificial" frames and make the image generated from the console look smoother than it should. This is a very unique solution in the world of TVs – competing systems usually do not offer this – and that’s why Samsung has had a strong selling point among gamers for years, even despite the lack of support for the still niche Dolby Vision in games.

So why do we refer to it as an "almost" perfect screen? Unfortunately, similar to previous Samsung models, we noticed an issue with the lack of HGiG functionality. This solution allows the TV to leave tone mapping control to the console, so that games look exactly as intended by the developers. What’s worse, this feature was present before and disappeared after software updates. Instead of minor fixes, we got a step back. It's a shame, because without this lack, the QN90F could really be the ideal choice for gamers in the miniLED category.
